jsencrypt 公钥加密 Java 私钥解密 RSA加密

Java生成密钥对

采用hutool工具生成

KeyPair keyPair = SecureUtil.generateKeyPair("RSA");
PrivateKey aPrivate = keyPair.getPrivate();
String privateEncode = Base64.encodeUrlSafe(aPrivate.getEncoded());
String publicEncode = Base64.encodeUrlSafe(keyPair.getPublic().getEncoded());

Java私钥解密

String privateKey="";
String publicKey="";
String rsaPassword="";
RSA rsa=new RSA(privateKey,null);
byte[] encrypt = rsa.encrypt(StrUtil.bytes(password, CharsetUtil.UTF_8), KeyType.PublicKey);
String  decrypt2= rsa.decryptStr(rsaPassword, KeyType.PrivateKey); 
System.out.println("解密后："+decrypt2);

提示：RSA对象为Hutool工具对象，初始化只用其中一个密钥即可，不要指定算法。

错误示范：

RSA rsa=new RSA("RSA",privateKey,null);
